In fact, the code uses a
the
tag. For example, if you wanted to display text indicating the final item from an RSS feed,
you??™d use code like this:
Last item:
The test attribute checks to see if the position() function??”which refers to the current item??”is the
same as the one the last() function returns and, if so, displays the text. To apply the XSLT Conditional
Region object, follow these steps:

Integrating with XML and XSLT 32
1. Select the text, image, page object, or code you want to make conditional in either Design or
Code view.
2. From the Insert bar??™s XSLT category, choose Conditional Region.
3. When the Conditional Region dialog box opens, enter the condition to evaluate in the Test field
(see Figure 32-9).

Display or hide anything in an XSL fragment through the XSLT Conditional Region object.
4. Click OK.
While the XSLT Conditional Region object displays or doesn??™t display some code based on a single condition,
the Multiple Conditional Region is much more flexible. Although the Multiple Conditional Region
object initially tests a single condition, it provides alternative output leading to an either/or code output.
For example, say again you wanted to test for the final item and note it as such when it appears, but you
also wanted to display other text, that is, Next item:, until it appears.
